This is identical to our other Picatinny quad-rails except the weight-saving cutouts (sometimes called Speed Holes) are slots-shaped for a different look.

This is a standard free-floated quad-rail for the AR-15/M-16 platform. It is a free-float design, but a cap (sold separately) may be installed to close the front if your mission requires this.

  • Has an overhang to line up with the rail on a flat top upper if you have a bit of patience.
